Found in central Costa Rica in wet cloud forests at elevations of 1800 to 2000 meters as a medium to large sized, cool growing epiphyte with reed-like, terete, straight stems carrying on the apical half, elliptic to lanceolate, acute to acuminate, margin entire leaves with a smooth, tubular sheath that blooms in the late spring and early summer on a terminal, erect, arising on a mature cane, paniculate, suberect to arcuate, to 8" [to 20 cm] long, several to many flowered inflorescence with triangular, acuminate, longer to much shorter than the ovary floral bracts carrying simultaneously opening, resupinate flowers

"Epidendrum horichii is part of the GROUP Pseudepidendrum SUBGROUP Paniculatum characterized by the caespitose habit with cane-like stems carrying acute to acuminate leaves usually booming on an apical inflorescence and carrying flowers with filiform petals, and a usually 3 lobed lip with 3 parallel fleshy keels, with the apical lobe often bifurcate and the "bird wing" type pollina. The species is recognized by its simultaneous green and white flowers, immaculate or sometimes with a solid, light pink blotch on the disc, lip wider across the apical lobes than across the basal lobes, which are obliquely subquadrate, the sepals 9 mm long. Epidendrum subnutans Ames & C. Schweinf. has smaller, successive, flowers with sepals .18 to .28" [4.5 to 6.1 mm]. Epidendrum longibracteatum Hágsater, has still smaller flowers with sepals .136 to .2" [3.4 to 5.0 mm] and the floral bracts are much longer than the ovaries. Epidendrum piliferum has simultaneous, larger flowers with sepals .52 to .56" [13 to 14 mm], disc dotted with deep purple." Hagsater etal 1999
